Muscle Hunters

From Yu-Gi-Oh!

The Muscle Hunters are a group of thugs hired by the Junky Scorpion store owner to steal back expensive sports shoes he sells, including Air Muscle.

The members are unnamed in the manga, but called Venom A, Venom B and Venom C in the Dungeon Dice Monsters video game.

They once attacked Katsuya Jonouchi, Hiroto Honda and Yugi Mutou from behind and stole Jonouchi's Air Muscle shoes. Jonouchi and Honda tracked them down later at the arcade and beat them, while fighting face to face. The Muscle Hunters revealed that they'd been payed by the store owner.
